Abstract

563,347. Pipettes. LANGLEY, T. W., and TECALEMIT, Ltd. Oct. 16, 1942, No. 14553. [Class 1 (i)] A pipette into which a definite amount of liquid enters upon immersion, comprises a measuring vessel 1 connected at its upper end 4 to a downwardly extending open-ended tube 5. The amount of liquid entering is determined by the height of the opening 8 which is sealed when it dips into the liquid. The liquid is retained in the tube by pinching the rubber connection 7. In a modification, Fig. 2, the air-tube 13 is inside the other tube 14.
